In the original 1978 Halloween, we get a chilling one-liner: Dr. Loomis calls him "purely and simply evil." That’s it. No trauma, no bad childhood, no bullied past—just a cosmic, unexplainable void inside a six-year-old boy.
Why? Because the filmmakers wanted to scare you in a way no backstory could. Evil without a reason is terrifying. It’s like finding a spider in your cereal—no logic, just why?! And that’s the genius: sometimes the best answer is no answer at all.
The Rebooted Answers: A Mess of Motivation
Later movies (especially the 2018 reboot trilogy) tried to explain it. They suggested he killed his sister because he was… a sociopath? A puppet of a cult? A product of a broken home? Honestly, these answers feel like trying to explain why a hurricane hates your picnic.
Here’s the twist: each explanation is less scary than the original mystery. When you give evil a reason, you tame it. You box it up. And suddenly, Michael isn’t a monster—he’s just a problem you can solve. But real life doesn’t work that way, does it?
